Almost all chorus pedals are made for guitar and their effect is very weak on the low frequencies produced by the bass. This pedal is made for bass, with the full, intact chorus effect going all the way to low B on a 5-string. It has true stereo operation; 2 switchable, independent chorus channels with indicator LEDs; an integrated, regulated 12V power supply; plus On and Select footswitches.

I have tried several chorus pedals, including Boss. I own a Boss and the Carl Martin and I have chosen to place the Carl Martin in my chain while the Boss is gathering dust. The Carl Martin is simple and effective, with clean sound and no significant loss or boost of any frequencies, the way a chorus pedal should be. But the main feature I like is the ability to switch between two settings. I use a fast rate for some parts of certain songs and a slow rate for others, so now I don't need to fiddle with the knobs between songs. Good choice overall but does not run on batteries so consider if that works for you before buying.
